Final answer:
The Rational Method is not represented by any of the given options. The correct equation for the Rational Method, used in hydrology to estimate stormwater runoff, is Q = CiA. The equations given in the question relate to different fields and do not pertain to the Rational Method.
Step-by-step explanation:
The equation for the Rational Method is not explicitly listed among the options provided in the question. However, for clarification, the Rational Method is a formula used in engineering, specifically in hydrology, to estimate the peak discharge of stormwater runoff for a specific area. The standard equation used in the Rational Method is Q = CiA, where Q represents the peak discharge rate, C is the runoff coefficient, i is the rainfall intensity, and A is the drainage area.
None of the equations listed in the question (A. QP=C i A, B. D=rt, C. A2+B2=C2, D. I=prt) match the Rational Method equation. It is essential to clarify this with additional context or rectify any potential errors in the options provided. Additionally, equations such as D = √2 Rh and the one involving the reaction quotient, though relevant to their respective fields, are not associated with the Rational Method.
